Accounting Firm Recommendations Wanted

Family owned US Corporation is studying the feasibility of taking over approximately 15 to 20 retail locations scattered along both the Pacific Ocean Resorts and also Caribbean Resorts. Looking to identify a full service Accounting Firm to handle the filing of all required business documentation and then all ongoing reporting related to having Mexican Tax Obligations, Mexican Bank Accounts and a fair number of employee reporting requirements.

Since said firm would have to communicate with our US based accounting department without any Spanish skills, it would be a requirement that one or more account people from within the accounting firm would need to be fluent in English.

Along similar lines, any recommended Customs Brokers to handle clearing merchandise from the US for these locations are also being researched.

Any recommendations either posted publicly or via private message would be most appreciated!
